Quantum phase transitions without thermodynamic limits
Dorje C. Brody, Daniel W. Hook, Lane P. Hughston
A new microcanonical equilibrium state is introduced for quantum systems with finite-dimensional state spaces. Equilibrium is characterised by a uniform distribution on a level sur…
Exactly solvable quantum state reduction models with time-dependent coupling
Dorje C. Brody, Irene C. Constantinou, James D. C. Dear +1
A closed-form solution to the energy-based stochastic Schrodinger equation with a time-dependent coupling is obtained. The solution is algebraic in character, and is expressed dire…
Quantum noise and stochastic reduction
Dorje C. Brody, Lane P. Hughston
In standard nonrelativistic quantum mechanics the expectation of the energy is a conserved quantity. It is possible to extend the dynamical law associated with the evolution of a q…
Finite-time stochastic reduction models
Dorje C. Brody, Lane P. Hughston
A new energy-based stochastic extension of the Schrodinger equation for which the wave function collapses after the passage of a finite amount of time is proposed. An exact closed-…
Twistor cosmology and quantum space-time
Dorje C. Brody, Lane. P. Hughston
The purpose of this paper is to present a model of a quantum space-time in which the global symmetries of space-time are unified in a coherent manner with the internal symmetries a…
